INSULATOR-SUPPORT.

Specication of Letters Patent.

Patented July 9, 1918.

Application led April 21, 1917. Serial No. 163,557.

To all 'whom it may concem:

Be it known that I, WALTER S. MATER, a citizen of the United States, residing in the city of Philadelphia. county of Philadelphia, and State of Pennsylvania, have invented certain Improvements in Insulator- Supports, of which the following is a specication.

My inventi'on is a. simple, inexpensive and readily adjustable device for holding an insulator securely in any desired position, and it is characterized by its means for clamping it firmly to carrying means, such as a metal shape, and clamping the insulator firmly in various angular positions, permitting a universal adjustment of the insulator.

The characteristic features of the invention are fully disclosed in the following description and the accompanying drawings in illustration thereof.

In the drawings, Figure l is a front elevation of a. form of my improved device Xed to a leg of an angle iron; Fig. 2 is a side elevation of the same device with the angle iron shown in section; Fig. 3 is a. sectional view taken on the line 3-3 of Fig. 1; Fig. 4 is a plan view of the detached device; and Fig. 5 is a front elevation of a modified construction.

As illustrated in the drawings, my improved device comprises a hollow body or barrel 1 having the jaws 1 and 1b extending laterally therefrom and containirlidg he sposed oppositely to the jaws; the jaw 1n being serrated on its inner surface, the jaw 1b containing the set screw 2 or the wedge, 3, and the bearings 1d being externally ser- This device is adapted to be fixed to the shape 4 by placing the jaws 1a and 1b on opposite sides of a leg thereof and drawing up the screw 2 or the wedge 3 firmly against the leg.

The insulator 5 is connected to the body 1 by a bolt 6 which passes through the axis of the insulator, a; shoe 7, the slot 1c and a nut 8, the shoe, against which the insulator bears, having a serrated curvedbearing adapted for engaging the serrations of the bearings ld and the nut being movable in and prevented from turning by the angular ways 1 within the barrel on opposite sides of the slot 1.

The bolt v6 has a screw head 6, countersunk in the insulator, and is adapted to be turned by a screw driver to free the engagements of the parts 7 and 8 with the exterior and interior surfaces of the bearings 1d, when the parts 5, 6, 7, and 8 can be adjusted together to the various relatively angular positions between the limits of the slot 1c and set securely in the desired position by screwing in the bolt.

Having described my invention, I claim:

An insulator and a support therefor comprising a body provided with jaws for fixing it to carrying means, bearings separated by a slot and guide ways within said bearings, in comblnation with a nut movable within and controlled by said ways, a shoe supporting said insulator and engaging said bearings, and a bolt passing through said insulator, shoe and slot into engagement with said nut.

In testimony whereof I have hereunto set my namethis 13 day of A ril, 1917.

WALTE S. MAYER.
